Genuine Royal Enfield Bullet 350 UCE Kick Start Main Wiring Harness + Tail Lamp Harness Kit – 888310

Royal Enfield 888310 is the Main Cable + Tail Lamp (TL) Harness Kit for Bullet 350 UCE (Kick Start)—the complete wiring loom set that links your bike’s main electrical circuit to key components and the rear/tail-lamp section. It is listed as a certified genuine Royal Enfield spare part and is intended to match factory routing, connector layout, and overall loom length—critical for preventing loose connections, random fuse blows, intermittent lighting, and charging/ignition cut issues that often come from old, heat-damaged, or “jointed” wiring. 

This kit is the correct solution when your Bullet’s wiring has become brittle, has multiple repairs/tapes, or you are restoring the bike and want OE-spec reliability rather than aftermarket looms that may have mismatched couplers or incorrect branch lengths. Competitor pages often publish unclear titles (or “???” text), so your listing will rank better by clearly targeting “Bullet 350 UCE Kick Start wiring harness / wiring loom / tail light harness” along with the part number 888310.
